LINRAD USER DATA BANK

Introduction

LINRAD is an early attempt to get into this new field of qualified signal processing,
it is NOT just a DSP package for EME enthusiasts.

It is a weak siganl receiving software and hardware package. Applications go from VLF to uWave,
From EME, to QRP, Amateur Radio contesting, Aurora, monitoring of beacons, spectrum analyses,
frequency measurement, and other applications.

LINRAD is using the LINUX Operating System as its platform. Most of us are not familiar
with Linux, its many versions
and flexibility. Recently, the basic installation of Linux on a standard PC has become quite straight forward. Most so-called
distributions provide good instructions on how to go about it.

Linux is quite flexibility and powerful at times and it requires more understanding by the user. There is however a large amount
of information available.

Most good things come for a price, either in real money or intellectual effort!

The target here is to report on experiences with LINUX, the installation of the operating system and the adaptation to the LINRAD
hardware.

Linrad is using 2 or 3 cards depending on the user's preferences. The "normal" usage, with a conventional transceiver is with two cards.

It is only, when using the Delta 44 soundcard that one needs a second card for the audio output because the Delta 44 does not allow
the input and output sampling rates to be different. (and some day the Delta 44 output will be fine for the tx side)

A video card is used for the processing of the graphics. Some, if not most of the problems during installation and setup are related
to the type and manufacturer of these cards. It could be beneficial to research the internet or inquire other LINRAD users about the
usage of potential audio and video cards, the audio cards in particular. ( Look for the availability of card drivers under LINUX )

Users of LINRAD might use different LINUX distributions and versions, different PC's with RAM and CPU's.

If one follows the work that has been done under Linux and by the community of LINUX users in many areas, it is clear that LINUX
has many advantages, though it may require extra reading and effort for some of us, the new users of LINUX.

We like to report here on experiences. In order to do this we need input from users and potential users. That is

YOU
.

The presentation of the data is experimental at this point and as we move along it might change.

Use your "SAVE LINK AS" in your browser to DOWNLOAD. This is not a REAL AUDIO File.

This is the new RPM for linrad 01-00.
It is for

Mandrake 8.x (although it SHOULD work for
others, no guarantees.)
Since this is a binary distribution, you no longer need gcc, nasm, or any of the
development libraries installed.
Performance won't be as good as if you compiled your own, but it should be
easier,,, just type:
